Declining Language

I just want to bring up the topic of language which was discussed briefly last week. Do you think it is good that the world is loosing languages every year? Are there benefits from having so many languages in the world or is it just a hassle? Should it be more of a requirement for kids to learn and be able to speak another language? I think that knowing more than your native language is a very good thing, especially how the world is becoming more connected and globalized. An interesting thing about language is that you can't always say the exact same thing in another language because of it's vocabulary. This is just an interesting thing to think about, especially since so many languages are being forgotten.
